π Where Does the Sidereal Zodiac Begin? SOR Starts With Evidence, Not a Selected Ayanamsa
One source-governed Revati-Ashvini / Zeta Piscium bounded origin constraint is now admitted for J2000 — without claiming a universal ayanamsa. π SOR — Structural Sidereal Origin Resolver The question sounds simple: Where does the sidereal zodiac begin? The natural answer may seem to be: Choose an ayanamsa. Enter it into the software. Calculate the chart. But that begins after a more fundamental question has already been answered — or assumed: What evidence supports admitting that origin claim? An ayanamsa may be familiar. It may be widely used. It may produce expected charts. It may be numerically close to another known value. But none of those facts, by themselves, establish where the sidereal zodiac begins. SOR begins with a different principle: selected ayanamsa != automatically admitted sidereal origin Instead of selecting a named system first, SOR asks: What source statement is being used? What coordinate measure does that statement use? Which stellar object or system carries...
